With a packet of 1N60 diodes on my doorstep I was finally able to get one of the RCA "coffee table" sets up and running like a champ. Of course the full-recap helped too!
Anyone else notice though that the RCAs with the printed circuits seem to be tougher to troubleshoot and more prone to failure than the other makes of the mid to late 50s? I have several RCAs like that and they all have issues. On this one, RCA combined three resistive tracks onto a single substrate with press-on plastic knobs for the vertical adjustments. Once I had things going, I noticed the picture liked to tug and shake at the top and sure enough, part of the vert height trace had arced away. Not much you can do besides installing a real pot on the back.
But hey, it works!
This one also has the New Vista script on the front, but I don't see any nuvistors. Interesting!
